Aiaplic'atibnfiled time 27, 1922, Seria11No.532,267.

VVatertown, in the county ofdefterson and 1 State oflVisconsin have invented certain new and useful. Improvements in h lerry-Gd Rounds; and I do hereby declare that the following is a full, clear, and exact descnption thereof. I

My invention reates to merry-go'rounds of the general type in which the motive power for revolving the sameis furnished by the persons riding thereon.

A general object of the invention includes the provlslon of a structure which s'so sup ported and balanced that the friotion'and consequent power required to operate the merry-go-round is reduced to the least pos sible amount. p j

The invention consistsfurtlier in certain structural details, which will be-hereinaiter explained in connection with the accompanying drawings and subsequently claimed.

In the drawings Figure 1 represents a vertical, sectional view of a portion of the merry-go-round.

Flgure 2 represents a plan VleVvflOf the same, and

Figure 3 is a detail view showing the connections by means of which the power is j be rocked by the occupant of the seat to rotransmitted. l

The device, of which my invention forms a part, comprises a vertical,,central post 5, which is preferably embedded in a baseGI Secured on this post near its lower end is a master gear 7, which, is securely maintained in horizontal position of concrete or the like.

by suitable braces 8. Journalled on the post above the master gear is a spider 9 having radially projecting arms 10, each of WhlCll carries at its outer end a seat 11 which is secured to the arm by a suitable bracket 12.

A journal box 13 is secured to the post/ near its upper end and is provided with ba l bearings 14: in which is journalled a hub 15. This hub is provided with an annular flange 16 which projects outwardly of the ournal box and to which are secured the upper ends] of a plurality of stay rods or cables l? and, the lower ends of these stay rods are con nected with the seats 11 to aid in supporting the same, thus relieving the strain on the arms 10. Certain ofthe rods 17 are secured to the backs 18 of the seats and the remaining rods are secured to the tongues 19, which by which it is driven.

.mounted a substantially vertical walking thereof within projectforwardly l romi the seats and which T MW Bonnier rIaoBsKY, or WATERTOWN, Wiscons n, ASSIGNOR or Quartets we w n are straddled by the person occupying the I same. I I j i Dependingtrom each of the arms .10 are a plurality of journal bearings 20 and 'alined therewith areaplurality of journal bear-- ings '21 which are secured to the bottom of the seat carried by the arm. A shaft 22 is journalled in the bearings 20 and 21 and carries at one end a pinion which is in mesh w th the master gear 7. The shaft 22- isprovlded with a pair of cranks 23 and 24L The tongue 19 of each seat is provided with a slot 25 within which is pivotally beam-26. Connect-ingro ds 27 and 28 are adjustably connected by means of the holes 29 to the walking beam on opposite sides of the pivot. The forward ends of the connecting rods are ournalled to the cranks 23 and 24:,

respectively, which are located underneath the next seat in :lront' of the one to which the walking beam is pivoted. The walking'beam is provided at its upperand lower ends with i the crossheads and 31, respectively,whioh may be engaged bythe hands and feet of the person occupying the seat. I

It will be understood thateach seat may be provided with a walkingbeam which may tate the crank shaft 22 through the medium of the connecting rods 27 and 28, thus caus ing the entire frame and seats supported thereby to revolve aboutithe center post 5.

It will be seen from the foregoing descrip tion that the construction which .I have devised is' very simple and may be readily,

1. In a device of the character described, a

centerpost having a master gear secured to the lower portion thereof, a frame revolubly.

mounted on said post, seats; carried by the frame, a crank shaft located adjacent each seat and journalled in the frame and operatively. connected with the master gear, each shaft having two cranks, a walking beam in front of eachseat; and a pair of connecting rods connecting opposite ends of the Walking 1 beam-to the cranks of the crank shaft associated with the next succeeding seat said; Walking beam 'heing providedwith means 'en-' gageable respectively "by the hands and feet of wperson occupying the seat. i I

' 2. In a device of the characterdescribed, a

center post, a master .ggear secured to the lower portion thereof, a spider journalled on the 90st above said' ear seats carried thereconnected to the master gear, 'eaich of said seatshaving a forwardly" projecting tongue, :1 Walking beam interr'nediately pivoted to said tongue and having means for engagement hythe hands and feet o1 a person in the seat for operating the same, and connecting rods pivotally connected at their forward ends to the respective cranks of the crank which is journalled nndernea-th the nextseat in front and adjnstahly connected attheir rear ends to the endsof saidwa'lkinghemn.

In testimonyithatl claim the foregoing-I have hereunto set my hand at Vntertown, in thecounty ofJefEe-rsonand State of Us consin.
